Fix scp interaction with windows server

locale machine - linux
remote machine - windows (with winsshd server)

Command line is ok:

		user@linux:~$scp ugl@192.168.10.188:C:/qwerty/file.exe /tmp
		ugl@192.168.10.188's password: 
		file.exe                                  100%   54KB  53.5KB/s   00:00

sshj before fix:

		public static void main(String[] args) throws Exception {
			String host = "192.168.10.188";
			String username = "ugl";
			String password = "123";
			String remotePath = "C:/qwerty/file.exe";
			String localPath = "/tmp/";
			SSHClient ssh = new SSHClient();
			ssh.setConnectTimeout(10);
			ssh.loadKnownHosts();
			ssh.connect(host);
			ssh.authPassword(username, password);
			ssh.newSCPFileTransfer().download(remotePath, new FileSystemFile(localPath));
			ssh.close();
		}
